Why You Shouldn’t Ignore Cracks in Your Autoglass

Before we dive into how to handle cracks, it’s important to understand why you should never ignore damage to your autoglass.

1. Safety Risk

Your windshield is a critical part of your car structural integrity. In the event of an accident, a cracked windshield is more likely to shatter, which can cause injury and reduce the overall safety of the vehicle. Cracks also obstruct your view, making it difficult to see clearly while driving, which increases the risk of accidents.

2. Prevents Further Damage

A small crack can quickly spread due to vibrations from driving, temperature changes, or additional impacts. Once the crack expands, it becomes more difficult and expensive to repair. Addressing the crack early can prevent it from spreading and save you money in the long run.

3. Legal Implications

Driving with a cracked windshield is illegal, especially if the damage obstructs your line of sight. You could face fines or be required to replace the windshield entirely if the damage isn’t fixed in a timely manner.

Step 1: Assess the Damage

The first step in dealing with an autoglass crack is assessing the type and severity of the damage. Not all cracks are the same, and knowing what you’re dealing with will help you decide whether a repair or replacement is necessary.

Types of Autoglass Damage

1. Chip: A small, localized piece of glass that has been removed from the windshield, often caused by debris like rocks or gravel hitting the glass.
2. Crack: A line that extends across the windshield. Cracks can vary in length and can spread over time.
3. Star Break: A type of crack that has a central point with smaller cracks radiating out, resembling a star.
4. Bullseye: A circular chip with a distinct impact point, often caused by a direct hit from a small object.
5. Combination Break: A mix of different types of damage, such as a chip with cracks radiating from it.

Can It Be Repaired or Does It Need Replacement?

Once you’ve identified the type of damage, you’ll need to determine whether a repair is possible or if a full replacement is required.

• Small Chips or Cracks: If the damage is less than a few inches long and doesn’t obstruct your line of sight, a repair is often possible. Most small chips and cracks can be fixed using special resins that fill in the damaged area and restore the glass’s structural integrity.
• Large Cracks: If the crack is longer than a few inches or is located in your line of sight, it’s likely that you’ll need to replace the windshield. Large cracks weaken the entire windshield, making it unsafe to drive.
• Multiple Cracks: If there are several cracks or chips, or if the damage covers a large portion of the windshield, replacement is typically the best option.

Step 2: DIY Repair Options for Small Cracks

If your windshield has a small chip or crack, you may be able to fix it yourself with a DIY autoglass repair kit. These kits are available at most auto parts stores and can be a cost-effective solution for minor damage.

How to Use a DIY Autoglass Repair Kit

1. Clean the Area: Before you start, clean the area around the crack or chip to remove any dirt, dust, or debris. Use a gentle glass cleaner and a microfiber cloth.
2. Apply the Resin: Most repair kits come with a resin that’s specially formulated to bond with the glass. Follow the instructions provided with the kit to apply the resin to the damaged area.
3. Cure the Resin: After applying the resin, use a curing strip (usually included in the kit) and allow the resin to harden in the sunlight or under UV light.
4. Smooth and Polish: Once the resin has cured, use a razor blade or polishing tool to smooth out the area, ensuring that the surface of the glass is even.

While DIY kits are great for minor cracks and chips, they may not be sufficient for larger or more complex damage. If the repair doesn’t fully fix the crack, it’s best to consult a professional.

Step 3: Professional Autoglass Crack Repair

If the crack is too large for a DIY repair or if you’re unsure of how to fix it yourself, it’s time to seek professional help. A trained autoglass technician can assess the damage and provide a more permanent solution, whether through repair or replacement.

Benefits of Professional Repair

• Higher Quality Repairs: Professional technicians have access to specialized tools and high-quality resin that can make the crack nearly invisible and restore the strength of your windshield.
• Fast and Convenient: Many autoglass repair shops offer mobile services, meaning they’ll come to your home or workplace to fix the crack. The repair process usually takes less than an hour.
• Guaranteed Work: Most professional repairs come with a warranty, so if the crack spreads after the repair, you can get it fixed again without additional costs.

When to Replace the Windshield

If the crack is too large or in a dangerous area, such as directly in front of the driver’s view, replacing the windshield is the safest option. Windshield replacements are more expensive than repairs, but they ensure the structural integrity of your vehicle and keep you safe on the road.

Step 4: Preventing Future Cracks in Your Autoglass

Once you’ve repaired the crack in your autoglass, it’s important to take steps to prevent future damage. Here are some easy tips to protect your windshield from cracks and chips:

1. Avoid Following Large Trucks or Construction Vehicles

Large trucks or vehicles carrying loose debris can kick up rocks and gravel, causing chips or cracks in your windshield. Keep a safe distance from these vehicles to reduce the risk of damage.

2. Drive Carefully on Gravel Roads

Gravel roads are notorious for causing windshield damage. If you must drive on gravel, go slowly to avoid kicking up rocks, and stay a safe distance behind other cars.

3. Park in Sheltered Areas

Extreme weather conditions, such as hailstorms or strong winds, can cause damage to your autoglass. Whenever possible, park your car in a garage or under a covered area to protect it from the elements.

4. Replace Worn Wiper Blades

Old or damaged wiper blades can scrape against your windshield, leaving scratches that weaken the glass. Replace your wiper blades regularly to keep your windshield in good condition.

5. Avoid Rapid Temperature Changes

Sudden changes in temperature can cause cracks in your autoglass to spread. On hot days, avoid blasting the air conditioner directly onto the windshield, and in cold weather, don’t use boiling water to defrost the glass.

Conclusion:

By assessing the damage, using DIY repair kits for small cracks, and seeking professional help for larger issues, you can keep your windshield in top condition without the need for a full replacement. Regularly inspecting your windshield and taking preventive measures can help you avoid future damage and keep your car safe on the road. Remember, fixing cracks early not only saves you money but also ensures that your vehicle remains structurally sound and ready for the road.
